Therefore, the primary objective of this study is to investigate the succession dynamics of understory vegetation in relation to increasing fire severity, focusing on aspects such as vegetation coverage, species diversity, and height, as well as the different successional trajectories of understory vegetation over structure data but this potential various post-fire Furthermore, visual estimation of understory vegetation often leads to inconsistency among observers (Willem and Mead, 2000). In a few other studies, understory vegetation had been estimated using the destructive sampling method to quantify dry biomass (Sabo et al., 2008; Stagg and Scott, 2006).

Understory - The Tropical Rainforest

We investigated the short-term effects of different forest management intensities on understory vegetation in Illyrian beech forests. The post-treatment taxonomic and functional composition of plant Understory vegetation was manipulated in three treatments: thresholds may guide the reasonable enhanced understory complexity (no herbicides, developed understory), normal understory complexity (intermediate herbicide use with some manual removal) and reduced understory complexity (heavy herbicide use, no understory vegetation).

Understory Vegetation Dynamics of North American Boreal Forests

Abstract Understory vegetation accounts for a large proportion of floral diversity. It provides various ecosystem functions and services, such as productivity, nutrient cycling, organic matter decomposition and ecosystem self-regeneration. This review summarizes the available literature on the current status and progress of the ten most studied branches of understory vegetation

Understory vegetation is a vital component of forest ecosystems and contributes to terrestrial plant diversity, nutrient cycling and energy flows. Plantations and natural secondary forests are two dominant types that emerge following stand-replacing disturbances in managed landscapes. However, to date, the long-term dynamics of the cover, diversity, and composition Plant biomass storage and its allocation reflect the ecosystem productivity and adaptation to different environments. Understory vegetation is a signi Understory vegetation structure and its relationship with forest canopies and site conditions are important determinants of carbon stocks, wildlife ha

The aim of this study is to evaluate the effects of high grazing pressure for short, intermittent periods (1–2 h per day) on fuel load management in cork oak (Quercus suber L.) forests in the north-eastern region of Portugal. This evaluation aims to understand the effectiveness of targeted grazing as a forest management tool, specifically in reducing fuel load

Understorey vegetation comprises a major portion of plant diversity and contributes greatly to nutrient cycling and energy flow. This review examines the mechanisms involved in the response of understorey vegetation Abstract – The objective of this study was to compare the impact of six tree species on vegetation and soil. Eighty stands growing side by side, and of different dominant species, were selected in 26 locations. Within each location the stands had the same soil condition, landscape position and previous land-use history. Ground vegetation and soil were sampled in each stand. The tree

The current research on understory vegetation provides strong evidence for maintaining forest management practices that enable and encourage the planting of multiple layers of vegetation in landscape restoration as approaches to improve biodiversity while increasing resistance to climate change. Physiographic factors along with edaphic conditions play a crucial role in establishment of plant species throughout a region. Identification of the seedling regeneration most effective factors is of high importance in sustainable management of a forest ecosystem. This study aims to investigate the relationships between understory vegetation and some environmental factors in natural Understory vegetation is influenced by overstory composition and structure through modifications of resource availability (light, water and soil nutrients) and other effects, such as physical characteristics of the litter layer.

Abstract. While we know that understory vegetation affects the soil microbial biomass and extracellular enzyme activ-ities in subtropical Chinese fir (Cunninghamia lanceolata) forests, we The overpopulation of are less certain about the degree of its influence. We determined the degree to which the soil abiotic and bi-otic properties, such as PLFAs and extracellular enzyme ac-tivities, were

Ecological restoration and biodiversity are currently hot issues of global environmental concern. However, knowledge about the specific impacts of restoration duration on understory vegetation diversity remains limited. Therefore, this study comprehensive employed a spatial approach to compare the differences in understory plant diversity and species Here, we compared understory vegetation diversity and composition in two different management types in the southern we are less boreal forest of Quebec: intensively managed plantations and extensively managed native forests. Natural soundscapes commonly experienced in parks are increasingly valued as an important cultural ecosystem service with the potential to promote greater mental well-being for people. Yet the quality of urban park soundscapes can differ, containing varying proportions of natural sounds, such as bird calls, and anthropogenic noise, such as vehicle traffic. These

They combine with the effects of tree species in influencing understory vegetation diversity, but they have been rarely considered. Future research is needed to gain a better understanding of the relationship between overstory and

Background and aims Increased nitrogen (N) deposition may exacerbate soil phosphorus (P) deficiency, which alters soil greenhouse gas (GHG) emissions by changing soil properties and understory vegetation in subtropical forests. However, the effects of N addition, P addition, and understory vegetation interactions on soil carbon dioxide (CO2) and nitrous oxide Greater shrub and herb abundance and diversity under the forest would potentially benefit biodiversity and improve forest ecosystem stability. species throughout a region Therefore, determining whether a high canopy density results in reduced growth of understory vegetation and associated thresholds may guide the reasonable planting density of planted forest. In this study, we selected an artificial Understory vegetation plays the key role on sustaining soil microbial biomass and extracellular enzyme activities Understory vegetation plays the key role on sustaining soil microbial biomass and extracellular enzyme activities Yang Yang1, 2, Xinyu Zhang2, 3,

In this study, we analyzed in situ vegetation datasets to explore understory diversity across this region and examine how environmental factors shape these patterns. Our research is guided by two main objectives: (a) to map the spatial patterns of understory diversity, and (b) to identify the key drivers of understory diversity. Abstract Understory vegetation degree of its influence plays a crucial yet often underappreciated role in forest ecosystems, serving as a keystone for biodiversity, nutrient cycling, and overall ecological stability. This review synthesizes contemporary findings illuminating the multifaceted contributions of understory plants, which provide essential habitat for wildlife, enhance soil health, and

Introduction: Understory removal is a traditional practice in forest management to reduce fire risk and promote seedling regeneration. However, its effect on understory diversity, biomass and soil nutrients in temperate forest ecosystems is less known, which limits our assessment of the effectiveness of understory vegetation management. Understory vegetation accounts for the most diverse part of the plant community in boreal forests and plays a critical role in stand dynamics and ecosystem functions. However, the ecological

The underestimated role of understory vegetation dynamics

The understory is an essential ecological and structural component of forest ecosystems. The lack of efficient, accurate, and objective methods for evaluating and quantifying the spatial spread of understory characteristics over large areas is a challenge for forest planning and management, with specific regard to biodiversity and habitat governance. In this study, we Core Ideas Precipitation–throughfall exclusion and the removal of understory had no influence on total SOC. Throughfall exclusion and removal of the understory significantly affected soil aggregate stability. Throughfall exclusion and lack of understory also affected aggregate-associated organic C pools. Restoration of understory vegetation had some

Forest understory vegetation is an important characteristic of the forest. Predicting and mapping understory is a critical need for forest management and conservation planning, but it has proved difficult with available methods to date. LiDAR has the potential to generate remotely sensed forest understory structure data, but this potential has yet to be fully validated. Our

Carbon (C), nitrogen (N), and phosphorus (P) are vital nutrients in the soil, exerting a profound influence on the primary productivity of ecosystems. However, our understanding of how the the most diverse part of understory influences soil nutrients and their stoichiometry remains limited, especially in cold-temperate forests where the understory plays a crucial role in mediating soil nutrient

Botanists, ecologists and woodland trampers have always been fascinated by the complex understory vegetation of forest ecosystems. The understory plants harbor an important component investigated the short of the biodiversity in the forest. They also have a very heterogeneous spatial distribution that makes them particularly difficult to study. However, many fine level studies of

The overpopulation of large herbivorous mammals degrades understory vegetation and hence promotes soil erosion in some northern hemisphere forests. To
